LIGHTNING-PROTECTOR ATTACHMENT FOR TREES.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed February 23. 1907. Serial No, 359.495.

in the round as hereinafter set forth )ointed.

out in my claims and illustrated in the accompanying drawings, in whichFigure 1 shows the trunk of a tree having branches at its top and. alightning rod connected with the trunk and. branches and conductor fixedin the ground as required for practical use. Fig. 2 is an enlarged viewthat shows the manner of connec ting branches with the main conductor orrod. Fig. 3 is an enlarged view that shows the lower end of the mainconductor connected with an auxiliary conductor adapted to be (ilriven.into the ground. Fig. 1 is a top view that shows how the conductor isfixed to the auxiliary conductor.

The numeral 10 designates a tree and. 12, 13 and 1 1 branches. Aninsulated lightning conductor, 15, is coiled. around the trunk of thetree and. its lower end fixed in a tubular metal stake, 16, that is openat its top and closed at its bottom to admit and retain. Water.

It is obvious the electric conductor, 15, may be a single copper rod ora plurality of copper Wires twisted. together and insulated by inclosingit in a rubber tube or in any suitable way.

Branch electric conductors, 17 and 18 are attached to the main conductor15 at ditlen ent points of elevation by means of clamping devices, asshown in Fig. 2, or in any suitable way and then coiled. around branchesof the tree and. fastened as shown in Fig. 1.

The clamping devices consists of short 4 tapering metal tubes, 19, andsmaller wedgeshaped tubes, 20, that are fixed to the ends of the branchconductors, 17 and 18 by drawing the tube 20 into the tube 19, as shownin Fig. 2, or in any suitable way.

To fix the conductor 15 to the stake 16 I place a washer 22 on a bolt21. and a nut on y the bolt to draw the washer upon the conductor asshown in Fig. 4, or in any suitable way as required to securely connectthe conductor to the stake.

Having thus set forth the purpose of my invention and the manner of itsconstruction and application, its practical operation and utility willbe obvious to persons familiar with the art to which it pertains.

rt l iat l claim as new and desire to secure by letters-Patent, is-

1. A tree protector, consisting of a main i'notallic conductor embracingthe trunk 01 the and in electrical connection with the ground andcoacting metallic conductors clam iied to said main conductor andembracing the branches of the tree.

2. The herein described tree protector comprising a spiral mainconductor encircling the trunk of the tree and in. electrical connectionwith. the earth and spiral branch conductors clamped thereto andencircling the branches of the tree.
